IMPROVED LIQUID-COOLER.

Specification forming part of Letters Patent No. 54,016, dated April 17,1866.

To all whom it 'may concern:

Beit known that we, PHILIPP REUTLINGER and ALBIN HERBERT, ot'Williamsburg, in the county of Kings and State of New York, haveinvented a new and Improved Liquid- Cooler; and we do hereby declarethat the following is a full, clear, and exact description thereof,which will enable those skilled in the art to makeand use the saine,reference being had to the accompanying drawings, forming partot' thisspecification, in which- Figure l represents a plan or top View otl thisinvention. Fig. 2 is a sectional side elevation ot' the same. Fig. 3 isatransverse section ofthe double trough.

Similar letters of reference indicate corresponding parts.

This invention consists in the arrangement of a double trough brought inthe form ot' an open coil, in combination with suitable valves insertedin thelower half of said trough in suoli a manner that two liquids, oneto be cooled and the other to exert a cooling iniiuence, can be passedsimultaneously through said trough, the cooling-liquid through the upperand the liquid to be cooled through the lower part thereof, and that bymeans of the valves the speed of the liquid to be cooled can be adjustedso that the same runs down slower than the coolingliquid and any desireddegree of cooling effect can be obtained.

A represents a double trough, which is brought in the forin of an opencoil, as clearly showninthe drawings, so that the liquid poured in theupper end of said trough will run down through it and discharge at itsbottom end. The outer or upper half ofthe trough is open and aboutone-third larger than thelowcr closed part thereof', as shown in Fig. 3,so that the coolin g-liquid passing down through the outer half will becapable of absorbing the heat from the liquid to be cooled, which passesdown through the lower half of the trough.

The speed ot' the liquid to be cooled, as the same descends through thelower halt' of the trough, is regulated by means of one or more valves,B, which are applied at certain intervals, and which serve to close moreor less said lower portion ot' the trough. By this arrangement theliquid to be cooled can be made to run down much slower than thecooling-liquid and any desired degree of cooling eiitect can beobtained.

The cooling-liquid discharges through the spout (l, and the liquid to hecooled through the spoilt D, which is provided with a suitable faucetand so arranged that a hose can be attached to it for the purpose ofremoving the cooled liquid.

This liquid-cooler is particularly intended for brewers ot' beer andother liquors, and the hot beer on being passed through the lower halfot' the trough can vbe cooled with the greatest ease and facility,ice-water being employed as the cooling liquid.

The lower half of the trough is readily cleaned by blowing steam throughit or by means ot' sod a-water, if desired.

What we claim as new, and desire to secure by Letters Patent, is-

The arrangement of the double trough A, formed in an open coil, incombination with regulating-valves B, constructed and operatingsubstantially as and for the purpose described.
